Question

Which property of a colloidal solution is independent of charge on the colloidal particles?

• A. Electro-osmosis
• B. Tyndall effect
• C. Coagulation
• D. Electrophoresis

Answer 1

The correct option is B Tyndall effect

Tyndall effect is independent of the charge on the colloidal particles. It is an optical property and it depends on the size of the colloidal particles. The Tyndall effect, also known as Tyndall scattering, is light scattering by particles in a colloid or particles in a fine suspension. However, electro-osmosis, coagulation and electrophoresis depends on the charge on the colloidal particles. These are electrical properties.
